Compute both parts of given question:
Question: A 2.5kg block slides with a speed of 1.0m/s on a frictionless horizontal surface until it encounters a spring.
Part I: If the block compresses the spring 4.8 cm before coming to rest, what is the force constant of the spring?
k= N/m
Part II: What initial speed should the block have to compress the spring by 1.2 cm?
v= m/s
Please keep it short and simple and please no copy and paste. Thanks.
